Frequently, exposure data are measured over time on a grid of discrete values that collectively define a functional observation. In many applications, researchers are interested in using these measurements as covariates to predict a scalar response in a regression setting, with interest focusing on the most biologically relevant time window of exposure. One example is in panel studies of the health effects of particulate matter (PM), where particle levels are measured over time. In such studies, there are many more values of the functional data than observations in the data set so that regularization of the corresponding functional regression coefficient ...

Reverse Engineering For Mobile Systems Forensics With Ares, John Tuttle, Robert J. Walls, Erik G. Learned-Miller, Brian Neil Levine 2009 University of Massachusetts - Amherst

Reverse Engineering For Mobile Systems Forensics With Ares, John Tuttle, Robert J. Walls, Erik G. Learned-Miller, Brian Neil Levine

Erik G Learned-Miller

We present Ares ,areverseengineeringtechniqueforassist- ing in the analysis of data recovered for the investigation of mobile and embedded systems. The focus of investigations into insider activity is most often on the data stored on the insider’s computers and digital devices — call logs, email messaging, calendar entries, text messages, and browser his- tory — rather than on the status of the system’s security. Ares is novel in that it uses a data-driven approach that in- corporates natural language processing techniques to infer the layout of input data that has been created according to some unknown specification. While some other reverse ...


Applications Of Operation Research To The Analysis For The Impacts Of The Transmission Line Capacity Limitation On Clean Power Development, Jinxu Ding 2009 Selected Works

Applications Of Operation Research To The Analysis For The Impacts Of The Transmission Line Capacity Limitation On Clean Power Development, Jinxu Ding

Jinxu Ding

As global warming has become an issue that
all human beings have to address, it is time to figure out
how to reform our power system such that we can reduce
the
CO
2
emission meanwhile stimulating the development of
clean energy, such as wind energy. Because wind energy is
not so dispatchable as fossil energy and it is always located
in remote areas far away from high-power-demand areas, it
is necessary to set up new transmission lines to transmit the
clean power to these power-hungry areas. In this paper, we
use a modeling framework (designed by ourselves [3]) to ...

Greening The Curriculum: Augmenting Engineering And Technology Courses With Sustainability Topics, Kurt A. Rosentrater, Elif Kongar 2009 United States Department of Agriculture

Greening The Curriculum: Augmenting Engineering And Technology Courses With Sustainability Topics, Kurt A. Rosentrater, Elif Kongar

Kurt A. Rosentrater

Duties of engineers and technologists often entail designing and implementing solutions to problems. It is their responsibility to be cognizant of the impacts of their designs on and thus, their accountability to society in general. They must also be aware of subsequent effects upon the environment. They need to be able to concurrently satisfy these often competing priorities as well as constraints specific to the technical challenges at hand. Responding to these contending forces are the growing fields of green engineering and sustainable engineering. Both of these areas encompass many concepts, ideas and tools all of which are essential for ...

Modeling Relations And Their Mentions Without Labeled Text, Sebastian Riedel, Limin Yao, Andrew McCallum 2009 University of Massachusetts - Amherst

Modeling Relations And Their Mentions Without Labeled Text, Sebastian Riedel, Limin Yao, Andrew Mccallum

Andrew McCallum

Several recent works on relation extraction have been applying the distant supervision paradigm: instead of relying on annotated text to learn how to predict relations, they employ existing knowledge bases (KBs) as source of supervision. Crucially, these approaches are trained based on the assumption that each sentence which mentions the two related entities is an expression of the given relation. Here we argue that this leads to noisy patterns that hurt precision, in particular if the knowledge base is not directly related to the text we are working with. We present a novel approach to distant supervision that can alleviate ...


Evolving Fluvial Response Of The Sandy River, Oregon, Following Removal Of Marmot Dam, Peter Richard Wilcock 2009 Utah State University

Evolving Fluvial Response Of The Sandy River, Oregon, Following Removal Of Marmot Dam, Peter Richard Wilcock

Peter Richard Wilcock

The October 2007 removal of Marmot Dam on the Sandy River, Oregon, triggered a rapid sequence of fluvial responses as ~730,000 m3 of sand and gravel that filled the former reservoir were suddenly exposed to an energetic river. Using direct measurements of sediment transport, photogrammetry, and repeat surveys between transport events, we monitored the erosion, transport, and redeposition of this sediment in the hours, days, and months following breaching. Measurements of suspended load and bedload documented an initial spike in the flux of fine suspended sediment in the minutes after breaching followed by high rates of suspended- and ...


Forced Patterns Near A Turing-Hopf Bifurcation, Chad M. Topaz, Anne Catlla 2009 Macalester College

Forced Patterns Near A Turing-Hopf Bifurcation, Chad M. Topaz, Anne Catlla

Chad M. Topaz

We study time-periodic forcing of spatially-extended patterns near a Turing-Hopf bifurcation point. A symmetry-based normal form analysis yields several predictions, including that (i) weak forcing near the intrinsic Hopf frequency enhances or suppresses the Turing amplitude by an amount that scales quadratically with the forcing strength, and (ii) the strongest effect is seen for forcing that is detuned from the Hopf frequency. To apply our results to specific models, we perform a perturbation analysis on general two-component reaction-diffusion systems, which reveals whether the forcing suppresses or enhances the spatial pattern. For the suppressing case, our results explain features of previous ...


Commissioning And Performance Of The Cms Pixel Tracker With Cosmic Ray, Serguei Chatrchyan Muons, stefan spanier 2009 University of Tennessee - Knoxville

Commissioning And Performance Of The Cms Pixel Tracker With Cosmic Ray, Serguei Chatrchyan Muons, Stefan Spanier

stefan spanier

The pixel detector of the Compact Muon Solenoid experiment consists of three barrel layers and two disks for each endcap. The detector was installed in summer 2008, commissioned with charge injections, and operated in the 3.8 T magnetic field during cosmic ray data taking. This paper reports on the first running experience and presents results on the pixel tracker performance, which are found to be in line with the design specifications of this detector. The transverse impact parameter resolution measured in a sample of high momentum muons is 18 microns.

Linh B Ngo

This paper studies the relationship between investments in High-Performance Computing (HPC) instrumentation and research competitiveness. Measures of institutional HPC investment are computed from data that is readily available from the Top 500 list, a list that has been published twice a year since 1993 that lists the fastest 500 computers in the world at that time. Institutions that are studied include US doctoral-granting institutions that fall into the very high or high research rankings according to the Carnegie Foundation classifications and additional institutions that have had entries in the Top 500 list. Research competitiveness is derived from federal funding data ...


The Tangled Tale Of Phase Space, David D. Nolte 2009 Purdue University

The Tangled Tale Of Phase Space, David D. Nolte

David D Nolte

(Preview of Chapter 6: Galileo Unbound: Oxford 2018) Phase space has been called one of the most powerful inventions of modern science.  But its historical origins are clouded in a tangle of independent discovery and mis-attributions that persist today.  This Physics Today article unravels the twisted tale of the discovery and the naming of phase space that began with Liouville in 1838, but by no means ended there, culminating in an encyclopedia article of 1911 that had unintended and lasting etymological side effects never intended by its authors.

Bismuth(Iii) Bromide In Organic Synthesis. A Catalytic Method For The Allylation Of Tetrahydrofuranyl And Tetrahydropyranyl Ethers, Ram S. Mohan, Scott W. Krabbe, Veronica V. Angeles

Ram S. Mohan

A bismuth bromide-catalyzed (10.0 mol %) multicomponent reaction involving the allylation of THF- and THP-ethers, followed by in situ derivatization with acetic anhydride to generate highly functionalized esters has been developed under solvent-free conditions. To the best of our knowledge, this is the first report of a catalytic procedure for the allylation of THF- and THP-ethers to yield ring-opened products.

Subhorizontal Fabric In Exhumed Continental Lower Crust And Implications For Lower Crustal Flow: Athabasca Granulite Terrane, Western Canadian Shield, Gregory Dumond, Philippe Goncalves, Michael L. Williams, Michael J. Jercinovic 2009 University of Massachusetts - Amherst

Subhorizontal Fabric In Exhumed Continental Lower Crust And Implications For Lower Crustal Flow: Athabasca Granulite Terrane, Western Canadian Shield, Gregory Dumond, Philippe Goncalves, Michael L. Williams, Michael J. Jercinovic

Michael J Jercinovic

The >20,000 km2 Athabasca granulite terrane is one of Earth's largest exposures of continental lower crust. The terrane is underlain by heterogeneous isobarically cooled orthogneisses termed the Mary batholith. A transect across the batholith documents early, penetrative subhorizontal to gently dipping gneissic foliation (S1). Kilometer- to meter-scale domains of S1 contain lineations (L1) defined by ribbons of recrystallized K-feldspar + plagioclase + quartz + amphibole ± orthopyroxene. L1 coincides with garnet aggregates, elongate mafic enclaves, and core-and-mantle structure in feldspar porphyroclasts. Lineations are coaxial with hinges of isoclinally folded layering (F1). L1 is interpreted as a composite mineral lineation with intersection and ...


Estimation Of The Area Of Sealed Soil Using Gis Technology And Remote Sensing, Stanisław Białousz, Przemysław Kupidura 2009 Warsaw University of Technology

Estimation Of The Area Of Sealed Soil Using Gis Technology And Remote Sensing, Stanisław Białousz, Przemysław Kupidura

Przemysław Kupidura

Soil sealing can be defined as the destruction or covering of soil by buildings, constructions and artificial layers completely or partly impermeable (asphalt, concrete, etc.) It is the most intense form of land consumption and is essentially an irreversible process. Soil is sealed when agricultural or other biologically land is taken into the built environment. It is also a continuing process within existing urban areas, especially where urban population and the density of built structures is increasing and residual inner-city green zones are reduced. The paper concerns the methodology for an estimation of the area of sealed soil using GIS ...
